HUMIDIFIEB.

Specification of Letters Pate'nt.

Patented-May'Z S,"1918.

To allwhom it may concern:

Be t known that W8,DAN1EL H. IOUNG and CHARLES Poems, citizens of the U'nitedSt-ates of America,-andresidents of h lan'c'hester, Delaware county, Iowa, have invented certain new and useful Improve- 'mentsin Humidifiers, of'which the follow- 'Fig. 3.

Similar numerals of reference denote corresponding parts throughout the several views.

25 denotes a rectangulai receiving tank, open at the top. "28"denotes a rectangular bottle, or supply tank, having a short neck 29, inverted and supported upon the upper end of the tank 25. A cork 30 is fittedinto said neck, and a tube 31 passed downwardly through the cork to depend into the receiving tank 35 and upwardly into the supply tank 28 for a short distance.

The numeral 1 denotes a relatively small boiler, closed at the bottom and open at the top, and having in its lower end a nipple 21, the tank 25 having a nipple 23 with a flexible rubber tube 22 fitted over both said nipples to effect communication between the tank 25 and the, boiler. The numeral 32 denotes an open-ended casin fitted about the boiler 1, the boiler being sli able lengthwise therethrough, and has an oflset part 17. The shaft 16 is mounted within the offset part 17 and has thereon a gear-wheel 14 within the part 17 which engages a rack 13 on the adjacent wall of said boiler, said shaft having on its outer end a knurled disk 15.

The numeral- 26 denotes an angular clamping body formed of a bar bent medially at a, right angle, and having bent over extremities on which are fixetlwshortjpieces or angle-bar 27. One limb of this clzunping device is fastened across thecasing 1732 fixedly by-means of pins 24. The casing, with its included movable boiler l,-maybe removably -mounted upon the supply tank '25-by means ofthis clamping device when the clamping device is positioned as shown insaid'Fig. 2with'the angle-bars 27 engagingdiagonally oppositeangles of said tank. In' order to prevent 'loss of heat :from the boiler l-to the tank 2fi, a plate ofsuitable material 19, which is a poor conductor of heat, i may be cemented or otherwise mounte'd-upouthe casin 32 between itand the "tank 25, there inay be :an air space between-the plate 1 9 and said tank, a plurality of spaces 20'being used therebetween. Referrin-g'now to Figs. 1 mid -3, Ihm'e supplied the 1 following described means for heating the fluid contents of the-boiler l'tola degree su'fiicient 'for rapid evaporation or even boiling: T hls lnea ns' consists otra pair of spaced electrodes 3 and 4,- whose extrem ities arefixed in a block of insulation 5. Said electrodes are positioned 'dependingly 'av'ithin 'the boiler l-soas to be i-mmersec a said electrodes are bent oppositely at right "angles andcarri'ed outwardly through slots 'Q'infthe upper end of the boiler.

The numerals 6 and 7 denote insulating sleeves mounted on the bent over ends of the electrodes to contact with the inner and outer walls of the boiler. The bent over ends of the electrodes are threaded to receive knurled discoidal nuts 8 and are employed to secure conductor terminals 9 and 10 in electric contact with the electrodes 3 and 4 respectively, as also to clamp the insulatin sleeves 6 and 7 tightly upon the boiler Wal s, it being understood that the electrodes, in passing through the slots 2, are kept out of contact with said boiler. The conductors 9 and 10 may be placed in circuit with any source of electrical current of sufficient capacity such as the three-phase alternating generator 12.

When the bottle or reservoir 28, after having been filled with Water and the closure 30 put in place, has been inverted and positioned upon the top of the supply tank 25 with the tube 31 depending thereinto, said tank becomes partially filled with water, and the water level is constantly maintained by reason of the operation of the well-known law, until the reservoir is emptied. Water flows from the tank 25 by way of the flexible conduit 22, into the boiler 1, partially immersing the electrodes 3 and 4 therein. hen the switch 33 is actuated in one direc' tion, circuit is closed from the generator 12, conductors 9 and 10, and electrodes 3 and 4:, through the fluid in the boiler 1, and the resistance of the latter results in its being rapidly heated to the boiling point. When desired, vapor or steam issuing from the open upper end of the boiler may be deflected horizontally by means of an openended hood 11 removably mounted in said boiler opening.

The heating of the fluid within the boiler may be expedited or retarded, as the case may be, by actuating the rack and pinion mechanism to either lower or elevate said boiler relative to the supply tank 25, which causes more or less of the lengths of said electrodes to be immersed in the fluid in the boiler because of the varying quantity of said fluid occasioned by said adjustment.

The casing 32 is preferably split vertically at 18 along its end opposite to the 0H- set part 17 to permit of the passage of the nipple 21 through the slit 18.

The conduit 22, being relatively long and flexible, permits of enough vertical movement to said boiler 1. y

Various modifications may be made in our humidifier, and other means of heating the boiler contents resorted to, without departing from the principle of our invention.

Attention is particularly called to the fact that while the supply tank 25 is very capacious, the boiler 1 is of relatively limited capacity, permitting the contents of the latter to be speedily heated without loss of heat to the contents of said tank. The device is especially adapted to humidity the atmosphere in such inclosures as cigar-cases, and electric current may be conveniently applied by using the ordinary -volt lighting circuit.

In Fig. 1 we have shown an encircling receptacle 81 about the boiler 1, which is located just below the top of the boiler, to catch any water boiling over therefrom.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is:

1. A humidifier, comprising a relatively small vessel open at the top, a relatively large supply-tank in communication therewith, and electrodes adjustably positioned within said vessel and in circuit with a source of electric current.

2. A humidifier, comprising a relatively large supply-tank, a relatively small boiler positioned near it, a casing in which said boiler is movably mounted, a clampingdevice detachably securing said casing upon said supply-tank, and a body positioned between said boiler and tank which is a poor conductor of heat.

.8. A humidifier, comprising a relatively small boiler, a relatively large supply-tank in communication therewith, a casing in which said boiler is movable, operative mechanism mounted in said casing for moving said boiler relatively to said supplytank, and means positioned within the boiler to heat its contents.
